Chapter Three • LD-V8000 Level II
programming will begin at address 0. If an argument is used, programming will
begin at the specified program address.
3.1.2 Screen Display
When the player is in Programming Mode, the monitor displays a four digit
(decimal) program address at the upper left of the screen. Mnemonics
representing one or more sequential program codes are displayed on a second line.
The displayed program address is the address of the rightmost byte of code
(command, argument digit, or data) displayed on the second line.
PRG. = 0011
Program Address
1 D I , 1 0 0 0 S C , 1 2 0 0 A S
As code is entered, the
display line shifts left.
Figure 3-A
Notice: Each argument digit or command takes up one byte.
The rightmost code byte is special, it's value may be replaced by a code entry from
the RCU. When a new code replaces an old code, the display shifts to the right so
that the next code byte in active memory is displayed as the rightmost mnemonic.
While in Programming Mode, the PROGRAM button does not enter a replacement
code, it preserves the codes displayed and just shifts the second line left to display
the next program code. By pressing the PROGRAM button repeatedly, entire
program segments can be reviewed and verified.
The displayed mnemonics differ depending upon the contents of each byte. Each
argument digit code is displayed as a one-digit numeric character. Other codes are
displayed in a three-character area followed by a comma. Most commands are
displayed as a 1, 2, or 3-character mnemonic. Other program codes are displayed as
a hexadecimal value preceded by an asterisk (i.e. *BA). A code value being entered
using the "Hex Code Entry" method starts to appear on screen in Hex, but the code's
mnemonic, if any, is used in the display as the code byte shifts left.
For example, the Set Frame Mode command has no single corresponding RCU
button. Appendix B, Alphabetical List of Level II Commands indicates that the
Hex code is 8E and the mnemonic is SFM. As the first Hex digit (the "8") is entered,
one can see an "*8" on the screen. However, as the second Hex digit (the "E") is
pressed, the display will shift to the left showing the SFM command mnemonic and
the displayed program address will be incremented by one.

This Program Code is at the
program address shown.
The code then shifts left.
